Plex have been busy updating the Plex desktop application adding including XBMC Frodo code, a new audio engine, Airplay support and 10bit H.264 video support. Plex have also renamed the application to Plex Home Theatre to avoid confusion with Plex Media Server.
Details from the Plex blog:
So what’s new? Well, we’ve re-synced to upstream XBMC code, to their “frodo” pre-release. But more than that, we’ve completely redone our integration so as to make future updates much, much easier. Our internal codename for the project was Fordo (because, let’s face it, a giant mountain with an impenetrable fortress inside sounds slightly more bad-ass than a little guy with hairy feet).
This brings us up to date with all the latest, which should finally resolve a number of long-standing issues, including A/V sync on SD files, high CPU usage when idle, and adds lots of cool stuff including:
HD audio support, via the new AudioEngine code, on operating systems which support it.
10bit H.264 video
Much improved rendering efficiency (“dirty regions”)
Many bug fixes to home screen, server detection
